At Mitchell Stainless in Hamilton, New Zealand, we supply stainless steel bars engineered for environments where corrosion resistance is critical. Our Stainless Steel 317L Bars feature increased molybdenum content compared to 316L, offering superior resistance to pitting and crevice corrosion, especially in chloride-rich environments. With low carbon content, they maintain excellent weldability and long-term durability. Backed by Mitchell Stainless’ commitment to quality and local expertise, 317L bars provide reliable performance in chemical, marine, and industrial applications, ensuring customers have a robust solution for demanding projects requiring both strength and corrosion resistance.
Stainless Steel 317L Bars are manufactured from a low-carbon austenitic stainless steel alloy containing chromium, nickel, and elevated molybdenum content. The additional molybdenum enhances resistance to pitting and crevice corrosion in aggressive chemical or chloride-rich environments. Low carbon content reduces the risk of carbide precipitation during welding, preserving corrosion resistance and structural integrity. These bars offer excellent tensile strength, toughness, and oxidation resistance across a broad temperature range, making them ideal for industrial, marine, and chemical processing applications.
